I 16 now and I want to join the marine when I graduate from highschool in 2018 for two reason?

One to orotect my country and everyone else. Two because i think if i join a girl at my school who im deeply in love with will be attracted to me again and stop ignoring me and whatever. Now i never had a girlfriend so i don't know nothing about girls but i reaseach and it said girls love guys in the marines so i just wanted a way to get her back what do you all think?
